- The center circle (0,0) And its radius
- The center circle (1, -1) And its radius
(Note: Write the answer as follows
Let the equation of circle is
Where, h and k are the x and y coordinates of the center of the circle.
And r is the radius of the circle.
Find the equation of circles by given information,
Multiply equation (1) by -1 and add both the equation:
Substitute the value of y in equation (1),
Five circles are placed in a rectangle as shown. If the length of the shorter side of the rectangle is 1, find the length of the other side.
